tf.compat.v1.keras.initializers.Ones

Initializer that generates tensors initialized to 1.

Migrate to TF2

This API is compatible with TF2 behavior and tf.function, and can be migrated immediately with tf.keras.initializers.ones.

Before:

>>> initializer = tf.compat.v1.keras.initializers.ones()
>>> initializer((1, 1))
<tf.Tensor: shape=(1, 1), dtype=float32, numpy=array([[1.]], dtype=float32)>

After:

>>> initializer = tf.keras.initializers.ones()
>>> initializer((1, 1))
<tf.Tensor: shape=(1, 1), dtype=float32, numpy=array([[1.]], dtype=float32)>

Methods

from_config

View source

Instantiates an initializer from a configuration dictionary.

Example:

initializer = RandomUniform(-1, 1)
config = initializer.get_config()
initializer = RandomUniform.from_config(config)

Args
config A Python dictionary. It will typically be the output of get_config.

Returns
An Initializer instance.

get_config

View source

Returns the configuration of the initializer as a JSON-serializable dict.

Returns
A JSON-serializable Python dict.

__call__

View source

Returns a tensor object initialized as specified by the initializer.

Args
shape Shape of the tensor.
dtype Optional dtype of the tensor. If not provided use the initializer dtype.
partition_info Optional information about the possible partitioning of a tensor.
